The novel highly efficient synthesis of sym-tetra-alkyl monothiopyrophosphates (RO)2P(O)SP(O) (OR′)2 based on the condensation of dialkoxyoxophosphoranesulphenyl chlorides with dialkyltrimethylsilyl phosphites is described.
The O-silylated dienolates of α,β-unsaturated ketones and aldehydes can be thiophosphorylated using O,O-dialkylchlorothiophosphonates and O,O-dialkylbromodithiophosphonates to give a new class of compounds thio- and dithiophosphates 1-4 in high yield.
